SASH-FASTE'NER.

SPEQIFICATION formingpart of Letters Patent No. 238,876, dated March 15,1881.

Application filed April 22, 1880. (Model.)

To all whom it may concern:

Be it known that I, HENRY FELLoWs, of Bloomington, in the county ofMonroe and State of Indiana, have invented a new and valuableImprovement in Sash-Locks; and I do hereby declare that the following isa full, clear, and exact description of the construction and operationof the same, reference be ing had to the annexed drawings, making a partof this specification, and to the letters and figures of referencemarked thereon.

Figure] of the drawings is a representation of a perspective view of asash and frame showing my sash-lock applied. Fig. 2 is a front view ofmy lock applied to a frame, and Fig. 3 is a perspective view of the samedetached.

Thisinvention has relation to sash-fasteners and it consists in theconstruction and novel arrangement of the vibratory catch-plate havin galong its upper portion a horizontal flange, and depending from it anarm at right angles to said 'flange having an outwardly bent endterminating in a laterally-projecting stud designed to engage, with theholes of a bored sash-strip, all as hereinafter shown and described.

The object of thiasinvention is to provide a simple and secureash-fastener which can be readily attached to tlie sash by oneholding-screw, and which requires no additional plates, boxes, orcastings, to put itin use. It is designed to Work in connection with aseries of round holes bored in the sash-strip of the window-frame,engaging with each hole in the line of the vertical diameter.

I am well aware that a gravitating catchplate having a projection toengage the shoulders or recesses of a plate attached .to thewindow-frame are well known, and therefore I make no broad claim to suchdevices, my invention being limited to particular devices,

which I will now proceed to describe, pointing them out especiallyin theclaim appended at the end of this specification.

In the accompanying drawings, the letter A designates a window-framehaving a sashstrip, I5, which is provided "with bored recesses or holesa at a sufficient distance from each other to afford convenient restsfor the sash 0, one of these holes being arranged near the sill.

E represents the gravitating catch-plate, a simple casting consisting ofa body, I), a horizontal outwardly-extending flange, 0, along the upperportion of said body, and an arm, d, extending downward from the innerend of the body next the sash-strip, and bent outward at its lower end,as shown at 0, so as to bring its terminal projection or lateral stud gin line with the vertical diameters of the holes a of the sash-strip,with which it is designed to engage. This catch-plate is pivoted to thesash by means of a screw, .9, which passes through said plate at itsangular portion or corner underneath the horizontal flange c. Thecatch-plate is designed to be pivoted near enough to the lower edge ofthe sash to be within reach of the thumb when the hand is placed underthe sash to raise or lower the same, the end of the thumb in thisoperation holding the horizontal flange by its upper or beveled surfaceagainst the sash-strip, along which it slides in the manner shown in thedrawings. When the flange is released the arm will fall and its lateralstud will enter the hole of the sash-strip. The flange 0 thereforeserves as a guide and guard for the thumb, and the outwardly-bent lowerend of the arm places the lateral stud or catch pr0-- jection at asnmcient distance out from the sash-strip to engage with holes bored insaid strip at a suflicient distance from its inner edge to be strong andcapable of holding the catch against strain.

I am aware that it has been proposed to construct gravity-latches with alift and locking-stud. In my device the body of the latch is deepenedbelow the lift, which keeps the finger oli' from the window, and the armprojecting downward has a bend, d, and the locking-stud is at rightangles there-to, so that the holes a in the casing can be made off fromthe sashway, and do not weaken the casing materially.

What I claim is- The gravity-catch plate E, having the body b, lift 0,at its top edge, arm d, extending downward and having the curve (1, andstud g, projecting outward at right angles to the curve 01,substantially as described.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
